@ServerResponseFilter with Throwable parameter is not called when REST resource is throwing an exception

[famod]

Describe the bug

https://quarkus.io/guides/resteasy-reactive#request-or-response-filters

implies that a @ServerResponseFilter method can handle exceptions, but that does not seem to be the case (see reproducer).

Expected behavior

Filter method should be called with the exception that was thrown in a rest resource method.

Actual behavior

Filter is not called with the exception that was thrown in a rest resource method.

How to Reproduce?

• clone https://github.com/famod/quarkus-quickstarts/tree/server-response-filer-exc
• cd opentelemetry-quickstart
• mvn clean install
• testFailEndpoint will fail because the trace-id header is missing (because the filter is not called)
• in TraceHeaderServerResponseFilter activate @ServerExceptionMapper -> test will pass
